- Utilizes sequential minor ii-V-i progressions, frequently modulating through descending minor key centers.
- Prevalent altered dominant 7th chords (e.g., G7alt, F7b13, Ab7b13) introduce rich chromatic tension and color.
- Employs a descending chromatic dominant chain (E7, Eb7, D7) as a sophisticated turnaround mechanism.
- The C minor (iii of Ab) area functions as a recurring tonal center, often established or returned to.
Improvisation Focus: Altered scale application over dominant 7th chords.
Difficulty Rating: 4 (Advanced Intermediate) - Demands proficient application of altered scales and swift adaptation to sequential minor key changes.
